Product Description:

The MDD093D-N-015-N2M-130PR1 synchronous motor is manufactured by Bosch Rexroth Indramat and belongs to the MDD Synchronous Motors series. Designed for direct coupling to digital drive controllers, the unit supplies commanded torque and speed for precision axis control in industrial automation. Its permanent-magnet rotor and internal position sensing support closed-loop regulation while maintaining compact dimensions that fit standard machine frames. This arrangement helps the motor deliver smooth acceleration, stable low-speed operation, and repeatable positioning in automated motion systems.

The mechanical interface uses a centering diameter of 130 mm, matching the flange pattern for size 093 frames. Standard balancing helps limit vibration during rotation, and the housing uses a standard design with no auxiliary cooling ducts. Power and feedback conductors exit on the right because the connectors are positioned on that side, and a single plug-style connector simplifies wiring. With motor length code D, the unit supplies a continuous standstill torque of 24.0 Nm without thermal derating. Under rated excitation, the rotor reaches 1500 rpm, favoring torque density over higher top speed. A shaft seal protects the interior, and the shaft end is supplied in standard form without a side B extension.

An integrated blocking brake is included to secure vertical or indexing loads; it delivers a holding torque of 11 Nm when engaged and releases automatically under drive command. Rotor position is reported by an integrated multi-turn absolute encoder, giving the controller full revolution tracking without external homing. Feedback signals are transmitted through the drive’s high-resolution digital servo feedback (DSF) channel, so motion accuracy is retained even during dynamic reversals. Mechanical power is transferred through a keyed shaft, and the keyway simplifies coupling to standard hubs while helping prevent slip under load. This arrangement is useful on axes that must retain position information after a restart and connect directly to common keyed transmission elements.
